Princeton University's physics department is known as one of the finest in the world, a member of a select group that includes MIT, Caltech, Harvard in the United States, and Cambridge and Oxford in the UK. Over the years I've taken my own students in nuclear physics classes from Virginia for a "right-of-spring" visit to Princeton, New Jersey. We've toured the Institute for Advanced Study where Einstein spent the last 23 years of his life and his home at 112 Mercer Street; the Princeton Plasma Physics Lab where pioneer nuclear fusion experiments have been carried out for the past five decades. [Whereas nuclear fission used in nuclear power reactors uses uranium and thorium, both in limited supply on earth, and the product is radioactive waste, nuclear fusion is virtually unlimited and produces no radioactive waste. One day the world will derive most of its electrical power from fusion generators. Fusion takes place at roughly 100 million Celsius. "Cold Fusion" is a sham!] And we always spent a day at the university's vaunted physics department, touring experiments and listening to some lectures.
In the photo, a prominent Princeton biophysicist was explaining the mechanism of the apparatus he had designed to simulate biological evolution. Built on a micro-scale, the apparatus contains a pattern of interconnected wells. Each well has enough volume to support a small population of bacteria, while the interconnections allow the population in each well to migrate out. From the outside edge, nutrients, antibiotics, and other things can be added to the wells. If the flow rate is chosen carefully, huge gradients in the amount of nutrient and antibiotics can be created. A bacterial population is placed at the center of the well. This is a very food-poor area, and the bacteria immediately migrate to the outside, where there is the largest amount of food. When some antibiotics are added to the solution, there are created three steep gradients; food, antibiotic, and bacterial populations all have their highest concentrations on the outside. This approach may have important application for cancer research.
A humorous touch was injected when the lecturer inadvertently wandered in front of the projector, where his forehead served as a secondary screen.
In the workshop is seen a group portrait of my students in front of Einstein's house. Two of them are identical twins (guess which two). I am in the red shirt in the far right.

Bonjour, cher ami Bulent,
Les avancées technologiques aident les professeurs et autres, toutefois, il y a parfois des inconvénients comme se voir inscrire des lettres qui peuvent prêter à rire.
Très bonne note d'accompagnement, comme toujours.

A mood composition with a touch of humour to it. Good light management with fine colours and clarity. Season's greetings.

Great photo from the Institute of Advanced Study. In The Netherlands we are very proud that the current director is a Dutch physicist. Really nice to see this lecturer at work, I know the problem of getting in the way of the projector light myself as well. The group photo in front of Einstein's house is great too!

nice the view of the interior of the University with the biophysicist in action as was explaining with the help if his projector the mechanism of his apparatus.I like the excellent light and colour management of the scene.
the best wishes for the New year ,Danos
PS thank you for wishes for Christmas as the coming New Year.

Indeed evolution, interesting scene.
I like frame, colors and letters on the head.
Warm regards and Merry Chistmas to you and your family also, Krzysztof.

Hello, dear Bulent! First of all my congratulations on your 200th photo from the US. And this is my latest comment in this year. Fine title and amazing scene, it makes me smile and reminds the school years, when we have often seen some movies and films in the classrooms. Sometime this process had some funny cases too. All the best wishes to you and your family in 2017! Merry Christmas! Serghei

Brilliant timing! It seems as if words were scrolling on the lecturer's forehead, so perfectly are they placed there. :-) Well taken in difficult lighting.

Génaile compo et vue quelle captage et vue quelle homem avec la projection en fond sur l'écran et sur sa tête sur son front très bien vu superbe scène.
Bravo et belle fêtes.

Have studied biology for my teaching certificate, I found your notes most interesting. Biological research is important to help fight diseases but, there is always a bit of me that worries about things going wrong! What used to be science fiction is, in many cases, now science reality!
It's a most amusing shot, especially when this guy is the expert, with everyone focussing upon him.
How fortunate that you had your camera handy!
My best wishes to you and your family for a very happy and peaceful Christmas,
As an aside, I love to hear your views on Donald Trump!

A good fun shot on a wintery day, thanks dear Bulent. Great how the letters crawl around the lecturer's forehead, like a cryptic bandana!
Thanks also for the added WS picture showing the house itself. They look like a nice group of students.

Lep pogled i trenutak, interesantan i dobar tekst ...
dobar rad, lepo pokazano, dobar kontrast i ostrina, lepe boje, lepo uhvacen trenutak. Dobar moderan nacin predvanja i izlaganja teme, interesantna projekcija preko lica predavaca.
Imajte lep dan, sve najbolje za vikend, srecno.
Beautiful view and the moment, interesting and good text ...
good work, beautifully shown, good contrast and sharpness, beautiful colors, beautiful moment captured. A good modern way of lectures for the presentation topics of interest projection across the face of lecturers.
Have a nice day, all the best for the weekend, good luck.

this looks like a mysterious image, full of riddles to me and in reality it's an illustration of answers and discoveries. I like how everything comes together so effectively in this fleeting moment, how the writing on the scientist's forehead looks like a cryptic message and how the light from the outside creeps into the intimate scene. The picture in the workshop is delightful, the choreography of the twins is great:) Congratulations and thank you!
All the best, Merry Christmas!

Certes cette scène fait sourire, vous l'avez capturer au bon moment, la note est très longue mais intéressante, très belle photo en WS, vos élèves devant cette très belle habitation de Einstein

very rarely we get to see the inside action in any university, Bulent, and this one is so diff. from the usual photos on TE. Of corse after it made sense after reading the note and seeing the WS attached.
My best regards and a happy new year,

Selamlar Bülent Bey,
This is a splendid interior photo. Light is well-managed in spite of the difficult conditions.
PS. I want to say "let's hope no more blood is shed in Turkey this year," but I know it is a futile hope. It'll get worse before it gets better. Let's hope that such events will bring sense to the middle of the road people in Turkey to make a difference for the better.
ChrisJ (118895) 2017-01-02 14:04
Good sharpness and the difficult internal lighting has been well managed. I suppose part of the o/h projector text adorning the man's head might be the word analysis? Tfs!

Hello Bulent I see a casual posture dressed of the basic clothing usually wore by passionate scientists who doesn't care about latest fashions. Did you realise the overattentive lecturer is bearing the Einstein hairdo! I also noticed he took good care of deaf people in the audience, showing on his forehead the essentials of his demonstration! Thanks for your kind words.
